A To al?, :hom it may concern,.-

Be it known that I, Jenn L. WILLIAMS, a

.citizen of the United States, residing, in thecity and county, ofPhiladelphia, State 'of Peimsylvania, have invented a new `and usefulSelf-Adj ust able Journ al, Crank, and Axle- Bearing, o`f which thefollowing is a specification.

My invention consists of a novel construction of sell-adjustablejournalor crank bearing in which the shaft will not bind or stick incase the bearing becomes heated and expands, and is especially adapted'for use with shafts which revolve at a high rate ol speed.

lt further consists in the interposition between the movable parts ofthe 4box of a bearing of a Wedge-shaped sliding key adapted to lic uponthe obliquefaoe or the movable part of said bearing and provided with asuitable spring whereby the sliding key is constantly forced forwardasthe journal or axle Wears away the contiguous face of the bearing,thus causing the boxes to always have substantially the same relation tothe shaft mounted therein.

It irther consists in the employment of a' 'fibrous Washer between theheads ot the bolts and the adjacent portions of the cap, said cap beingsuitably recessed, so that a lush joint is Jformed.

lt further consists in means 'for preventing forth.

Figure 1 represents a sectional elevation of an adjustable bearingembodying my inventionA Fig. 2 represents e sectional elevation ofanother embodiment 'thereof in which two wedge-shaped sliding keys areemployed. Fig. represents a plan view of one of the springs in detachedposition. Fig. 4 represents side elevation of Fig. i

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a connecting-rod to which the.pillow-block 2 is suitabl; secured, tlie same being integral therewith,ill desired.

3 designates upwardly-extending sides, through which ypass the bolts 4,provided with suitable nuts.

6 designa-tes a cap which is provided with recesses 7, within which arecontained the -librous washers 8, between which and the heads ot thebolts 4 are metal washers 9.

i l i l l l l .the inclined facerll or the movable bearing 10 and 1s.provided with a flange 13, whereby said key is retained in place. 14designates a chamber or recess extending into said key 12, in which isinserted the spring 15, one end of said spring engaging one end of saidrecess and the other end of said spring engaging the inner wall o1" theside rlhe spring 15 always tends to move the sliding keiT 12 fon wardlyor to the right, as seen in Fig. 1, so

that as the bearingP material of the bones Wears away the said boxeswill always have the same relation to the shaft, owing to the spring 15forcing the key 12 forwardly, and thus-moving the movable bearing 10downwardly 'against said shaft.

16 designates a lug or projection extending from the connecting-rod`1,which prevents any improper movement of the lower box 2.

In' the embodiment seen -in Fig. 3, 1.6 designates a connectingaodprovided with a lu 17,.'vhich engages the pillow-block 1S an preventsimproper movement thereof, said block 18 being provided with theupwardlyextending sides 19, tlirougl'i which pass the bolts or 'rodsS20, provided 1with suitable nuts 21 and by means of which the cap 22,pillowblock 1S, and the connecting-rod are secured together.

23 designates a recess in the cap which is metal Washer 25, said recessbeing;- of such depth that the metal washer is llush withthe surface ofthe cap when they parts are in assembled position.

2G designates the upper movable bearing, which is provided with asuitable flange 27, whereby it is retained in position.

28 designates a sliding key which is Wedgeshaped and provided with aflange 29, which l the inclined face othe Wedge 28. `This key is inplaced a fibrous washer 24 and a` IOO and said sides, nuts for saidbolts, and resiliently-actuated means interposed between said cap andsaid bearing for automatically takin up the Wear of said bearings.

5. n a journal-bearing, a fixed bearingblock having sides extendingtherefrom, a'eap yieldingly secured to said sides, a bearingblockmovable between said sides, keys interposed between said movablebearing-block and said cap=and each having an. inclined face coastingwith the inclined face of another key, springs adapted to automaticallyadvance said keys in o posite directions, a spring secured on the p aneface of each key, t ere being teeth on the contiguous face of said cap-and said movable bearing-block with which said springs enga e toprevent any rearward movement of sai keys.

6. In a device of the character described, a bearing-block having sidesextending there from, a bearing-block movable between said sides, a capyieldingly secured to said sides,

keys, each having an inclinediace coacting' with the inclined face ofanother key and interposed between saidca and said movablebearing-block, and provi ed With a recess on its plane face, springs foradvancing said keys in opposite directions, =a s ring secured in each ofsaid recesses, there eing a plurality oi armsof diierent. lengthsextending from said last-mention@` springs and teeth on said cap andmovable ybearing-block conti uousv said 'recesses with which one or moreo saidv arms engage to prevent rearward movement of said keys.

7. In a device ofthe character desir/filled, a

connecting-rod, a fixed bearing-block havy ing integral extending sidesconnected there-A with, means for preventing the im roper movementofsaid iixed bearing-bloei with respect to said rod, a cap yieldin lysecured to said sides, a movable bearing-b ock guided between said sidesand having flanges which prevent improper lateral movement ot saidmovable block, kes interposed between said movable bearinglock and saidcap, each having an inclined face coasting with the inclined face ofanother key and springs adapted to automatically advance said keys inopposite direct.
